Chalk, White Manufacturer,Supplier and Exporter in India

Chalk, White (Product Code: SLE/CS/022) is everyday extruded classroom chalk for writing on chalkboards and slates, packed 100 sticks to a box — 90 white for general writing and 10 yellow for headings, key words and emphasis. Each cylindrical stick is about 80mm long and 10mm in diameter, and the non-toxic mix is based on calcium carbonate with talcum powder and bentonite. It is supplied by Jain Scientific Equipments Pvt Ltd (ScienceLab), Ambala, a lab consumables supplier in India that also provides the boards and dusters it is used with.

Specifications

Typical Use

Teachers write lesson notes and working in white and switch to a yellow stick to underline the answer, the formula to remember or the day's homework, so key points stand out from across the room. Pupils use the same chalk on slates for letters, sums and quick sketches. To limit breakage, hold the stick near the writing end at a low angle and snap long sticks in half for small hands; keep boxes in a dry cupboard, as chalk absorbs moisture and becomes harder to write with when damp.

Because a single box serves a class for a period of regular use, schools usually order by the carton at the start of term and hand out boxes to each room, keeping a reserve to replenish individual students. Chalk is a routine line item in school supply and school science lab tenders in India, and the estimated 1.5kg box weight helps storekeepers plan shelf space and transport.
